Question

4/x+6y=10 adn 1/x-6y=5 find the value of p if p=5x

Answer 1

Answer:

p = 5/3

Step-by-step explanation:

4/x + 6y = 10 -------(1)

1/x - 6y = 5 --------(2)

using elimination method

on adding eq 1 and 2

4/x + 6y = 10

1/x - 6y = 5

4/x + 1/x = 15

(4+1)/x = 15

5/x = 15

5 = 15x

5/15 = x

1/3 = x

put x in eq 1

4(1/3) + 6y = 10

4/3 + 6y = 10

6y = 10 - 4/3

6y = (30 - 4)/3

6y = 26/3

y = 26/3 × 6

y = 156/3

y = 52

value of p

p = 5x

put x = 1/3

p = 5 × 1/3

p = 5/3
